Abstract: Control information for a flexible magnetic desk storage assembky (41, 42) is recorded on the periphery of the disk (42) in a region not used for recording data. The control information is read through the protective cover or envelope (41) which encloses the disk by means of a magnetic transducer (25) such as a four track audia cassette head which bears against the envelope. By recording index and sector pulses as part of the control information, hard sectoring can be inexpensively and accurately achieved. A recorded fixed frequency control signal can be read and used as part of the feedback loop in a phase locked oscillator used to control a d.c. motor driving the spindle. The control information can also include servo tracks which assist in registering the data transducer directly over data tracks on media which has changed its dimensions.

Abstract: An improved molded tray for a display stand is shaped to provide a rectangular planar product-support member, whose support area is free of structural invasion by other parts of the tray. The planar product-support member is reinforced by an integral, transverse, peripheral reinforcing flange that extends vertically along the periphery of the support member. Integral, tubular corner post-receiving means are provided adjacent each corner of the support member and tangent to the peripheral flange. Reinforcing strips extend parallel to and outwardly of the reinforcing flange to two opposed sides of the tray, and are integral with the tubular post-receiving means. A horizontal top wall joins the upper edges of the peripheral flange and each parallel reinforcing strip. The underside of the planar support member is reinforced by a grid of orthogonal ribs, and the support member is apertured, between the reinforcing ribs to reduce the amount of plastic used in forming the tray. The corner post-receiving means provides an upper, reduced height, stud concentric with a sleeve for cooperation with a tubular post, and a lower, extended length stud, concentric with a short sleeve for cooperation with a tubular post. The lower extended stud length provides versatile usage.

Abstract: Method and means for dispensing a meltable moisture curable composition from a package in which it is stored, without premature cure of the composition. The package comprises a tubular body portion closed at one end by means of a closure member, the closure member having an outlet opening and being sealingly secured to the body portion in such a manner as to leave a narrow annular space between the closure member and the tubular body portion and comprising at the other end a closure piston and a plain closure. A package is described and claimed which contains a solid meltable moisture curable adhesive composition. The rim of the piston projects towards the closure member and is in sliding sealing engagement with an inner wall of the body portion, the rim being received in the annular space between the body portion and the closure member as the piston approaches the closure member so that the container can be substantially completely emptied. Apparatus is described comprising a heated platen on which the package may be located for melting the composition adjacent the closure member, and a piston element for urging the closure piston of the package to expel melted composition through an exit port provided in the apparatus. The exit port is adapted to co-operate with the outlet of the package so as to provide a moisture proof seal between the outlet and the exit port means, and the apparatus is arranged for conducting melted composition from the exit port means to a dispenser nozzle without exposing the composition to atmosphere.

Abstract: In a multiple-measurement system, a weighted sum of the measurements is used to provide a selective image. An additional weighted sum is used to provide an increased signal-to-noise ratio of some desired parameter of the image. The high frequency components of the increased signal-to-noise ratio image are combined with the low frequency components of the selective image to provide a selective image with improved signal-to-noise ratio. The combining operation can utilize the ratios of the derivatives in each signal to provide the correct amount of high frequency signal at each transition.

The particular advantages of the present process are that, despite the substantially higher sputtering yield of bismuth oxide in the deposited layer compared with the other components in the layer, a specified layer composition can be reproducibly achieved, the deposited layers having a high homogeneity over the entire layer thickness. The high deposition rate achievable with this method is very advantageous in regard to an efficient manufacture.
